SPRING CUSHION-SUPPORT FOR CARRIAGE-SEAT BACKS.

SPECIFICATION forming part of Letters Patent No. 239,694, dated April 5, 1881.

Application filed September 23, 1880.

To all whom tt may concern:

Be it known that I, CHARLES C. BAILEY, of Wellsburg, Ohemun g county, NewYork, have invented a new and useful Improvement in Spring Cushion-Supports for Carriage-Seat Backs, of which the following is a specification.

Figure 1 is a perspective view of the improvement, shown as applied to a carriage-seat back. Fig. 2 is a vertical section, showing the arrangement of the spiral springs; and Fig. 3 is a horizontal section, showing the arrangement of the spiral springs.

Similar letters of reference indicatecorrespondin g parts.

The object of this invention is to furnish spring-supports for the cushions of carriageseat backs between the seat-backs and the lazy-backs, to hold the cushion out against the backs of persons riding in the seats and prevent the cushions from sagging, and which shall be so constructed that they can he attached to any seat-backs.

The invention consists in constructing "a spring cushion-support for carriage-seat backs of a spring-frame, having a dovetailed or T groove in its central bar, spiral springs to be interposed between the spring-frame and the rods that support the lazy-back, plates having studs for connecting the spiral springs with the spring-frame, and plates having grooved studs and clamps for connecting the spiral springs with the rods that support the lazyback, whereby the back-cushion will be supported and held out against the backs of the persons riding in the seat, as will be hereinafter fully described.

A represents the bottom, B the ends, and G the back, of a carriage-seat- D is the lazy-back, which is supported by the rodsE and the arms or braces F. The upper ends of the rods E are attached to the lazy-back D, and their lower ends are attached to the seat-back O and the bottom A. The rear ends of the arms or braces F are attached to the ends of the lazy-back D. The arms F are bent downward, forward and downward, and theirforward ends are attached to the ends B and bottom A of the seat. As thus far described there is nothing new in the con- 0 struction.

G is a spring-frame, formed by attaching three horizontal bars or springs to a number (Model) of upright bars or springs, as shown in Fig. 1. The spring-frame G is bent into any desired form, as the style of the carriageseat may re- 5 quire. The upper ends of some or all of the upright bars or springs of the spring-frame Gr project, and are attached to the lazy-back D. The upper and lower edges of the central horizontal bar of the springframe G are bent 6o rearward and inward to form a dovetailed or T groove to receive the plates H, upon the centers of which are formed, or to them are attached, studs I, to receive the smaller forward ends of the tapered or conical spiral 6 springs J. The forward ends of the spiral springs J, after being coiled around the studs 1, are passed through holes inthe plates H, and are riveted to the said plates. The rear or larger ends of the spiral springsJ are placed -in grooves in the studs K, formed upon or attached to the plates L, upon the rear sides of which are formed stationary jaws M, having half-round or half-diamond-shaped grooves formed in their faces to receive the rods E, 7 that support the lazy-back D, whether the rods E be round or oval.

To the faces of the stationary jaws M are fitted thefaces of the movable jaws N which have half-round grooves formed in their said faces to fit upon the rods E. The jaws M N are drawn together, to clamp the rods E, by i the screws 0, which pass through holes in the outer ends of one of the saidjaws and screw into screw-holes in the outer ends of the other jaws, as shown in Figs. 2 and 3. After the clamps M N 0 have been adjusted upon and secured to the rods E, and the plates and studs HI have been adjusted in the groove of the central bar of the spring-frame G, the bent or flanged edges of the said bar are bent inward or dented at'thc sides of the plates H, to keep the said plates H, and with them the ends of the springs J, in place.

With this construction the spring-frame G 5 can be secured to the seat-back, whether the rods E be straight or bent, and whatever he the style of the seat.

With this improvement the upholstering or back-cushion will be supported between the loo seat-back O and the lazy-back D and prevented from being pressed into the space between the said parts. The improvement also presses the cushion against and supports the backs of the persons sitting in the seat, and greatly increases their comfort in riding.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent-- 1. A spring cushion-support for carriageseat backs, constructed substantially as herein shown and described, consisting of the spring-frame G, having a dovetailed or T groove in its central bar, the plates H, having studs I, the spiral springs J, the plates L, having grooved studs K, and clamps M N O, to adapt the support to be applied to the back of a carriage-seat, as set forth.

v2. The combination, with the lazy-back D and the rods E, that connect the lazy-back with the back of a carriage-seat, of the springframe G, having a dovetailed or T groove in its central bar, the plates H, having studs I, the spiral springs J, the plates L, having 20 grooved studs K, and clamps M N O, substantially as herein shown and described.

3. The combination, with the spring-frame Gr, attached at its upper edge to the lazy-back D of a carriage-seat, and the rods E, that 25 support the lazy-back D, of the spiral springs J, connected at their ends with the said springframe and rods, substantially as herein shown and described, whereby the back-cushion of the carriage-seat is held out against the backs 0 of persons riding upon the seat, as set forth.
